INDIANAPOLIS—Robert Griffin III reaffirmed Sunday that he will be one of the fastest quarterbacks in NFL history.

Griffin was unofficially timed at 4.38 seconds on his second attempt in the 40-yard dash Sunday at the Combine, after doing 4.41 seconds in his first attempt. Later in the day, officials announced his time as 4.41.

Scouts already knew Griffin was a speedster. He was one of the country’s top hurdlers at Baylor before turning his attention strictly to football. However, Griffin’s speed will bring a different dynamic to the quarterback position for any team that drafts him.

It’s another dimension that gives Griffin at least a puncher’s chance to be the No. 1 pick in the draft, if the Colts are keeping an open mind whether to chose Griffin or Andrew Luck.

Neither Griffin nor Luck will throw Sunday, but Griffin has made a splash at the Combine with his personality and physical talent. Griffin is likely making quarterback-needy teams like the Browns and Redskins think even harder about trading up to get him.
